Abstract: The present invention is directed to multi-layered compositions for oral administration having at least one orally disintegrating layer and capable of maintaining layer cohesion. The present invention is also directed to methods of manufacturing such compositions.

Abstract: Methods for producing chewable emulsion compositions and compositions produced from such methods are disclosed. The emulsion base may be prepared by contacting an aqueous phase and a nonaqueous phase in the presence of an emulsifier. The aqueous phase is prepared under conditions that permit no substantial moisture loss and reduced viscosity. The methods permit preparing chewable compositions for delivering confectionary items, nutriceuticals, vitamins, minerals and therapeutically active agents. The compositions may be sugar-free or sugar-containing. The active agent may be added to the emulsion base at a lower temperature compared to the temperature at which either the aqueous or nonaqueous phase is formed. The compositions may be further coated with taste-masking materials, enteric coating materials, or slow-release materials. The compositions may be formed into compressible tablets, beads, granules, or otherwise generally known dosage forms.

Abstract: A chewing gum delivery system has nicotine, gum base and a buffer system with an improved release rate for the nicotine. The resulting delivery system advantageously provides a convenient, reliable, practical, and relatively painless system for delivering an active. The delivery system is capable of delivering initial and second doses of a craving reduction active or other actives (e.g., nicotine), the combination of which rapidly reduces cravings, or provides some other pharmacological effect, and provides the pharmacological effect or protection from such cravings over a prolonged period of time beyond the initial dose. Notably, the delivery system is capable of rapidly achieving a pharmacologically effective concentration of the active (e.g., nicotine) in the bloodstream (e.g.
